【提要】  通過(guò)鋼筋輕骨料混凝土開洞低剪力墻在低周反復(fù)荷載作用下的試驗(yàn)研究，探討了洞口大小和位置對(duì)剪力墻延性及耗能性能等的影響。由于洞口角部產(chǎn)生應(yīng)力集中，開洞墻體的開裂荷載小于未開洞墻體。洞口位置對(duì)于具有對(duì)稱墻肢的小開洞剪力墻極限承載力影響不大，但對(duì)結(jié)構(gòu)延性及耗能能力有一定的影響。
【關(guān)鍵詞】  輕骨料混凝土  開洞剪力墻  低周反復(fù)荷載
Experimental Research on Lightweight Aggregate Concrete Lowrise Shear Wall with Opening Under Low Frequency Cyclic Static Loading/Zhang Yankun1, Wang Shan1, Wang Fuming2(1 College of Architecture, North China Univ. of Technology, Beijing 100041, China; 2 Dept. Civ. Eng., Taiyuan Univ. of Technology, Taiyuan 030024, China)
Abstract:Three lightweight aggregate concrete lowrise shear walls with opening are tested under low frequency cyclic load. The influences of the size and location of openings on the ductility and energy dissipation are studied. Cracking load of shear wall with opening is lower than that without opening due to  stress concentration. The location of opening has little influence on the ultimate bearing capacity of shear wall with symmetrical wall limb, and influences the ductility and energy dissipation.
Keywords:lightweight aggregate concrete; shear wall with opening; low frequency cyclic load
